Distinct temperature dependence of gap in each of three phase regions. Red: low temperature gap. Blue: gap T>Tc. (A) In region A, NN gaps do not close across Tc. (B) In region B, NN gaps partially close at Tc, with AN pseudogap remaining T>Tc. OD80 is in phase region C at low temperature, but behaves like phase region B T>Tc. (C) He-lamp data. For p ≥ 0.22, gap closes everywhere on FS T>Tc.
